And as "bankruptcy is having more debt than you can afford," and "Washington is always on the verge of bankruptcy and always spending more than money than we have," he continued, "Maybe sending nation's leading expert in bankruptcy is a natural fit for Washington, D.C."

The problem with that, though, he said, is that Trump says his companies went bankrupt, but not him personally.

"Can you imagine him being president, saying the country went bankrupt but I didn't go bankrupt," Jindal told MacCallum.

The governor also attacked Trump on his conservative principles, calling the New Yorker a "man who believes in nothing but himself. Donald Trump is not conservative. He is not a liberal. He is a narcissist."

However, he contended that Republicans have a "unique opportunity, a once in lifetime opportunity, to get our country back [and] implement conservative ideas."

Jindal said he has decided to start attacking Trump directly because he thinks it is time to focus on proven conservative ideas.

"He doesn't believe in making America great again; he believes in making Donald Trump great," said Jindal. "Somebody has to say the emperor has got no clothes."
